Installation Instructions
Protection board wiring diagram
The wiring method of different manufacturers is different. Do not insert protection plate in the welding wiring
If only one string is used as an example, the same analogy can be used to connect the protection board with other string numbers
*lmportant note: Different manufacturers different connection, please buy the supporting line of the protection board, do not useother do not belong to the supporting line!! Due to the use of parts do not belong to the usual wiring, if there is a problem,will not accept return and replacement! *
Step 1: Connect cables to the protection board
First connect the B- and C- wires on the protection plate (the split-plate needs to be connected to P, and the same plate C- needs to be charged and discharged, and the wires must be thick). The B- wires should be welded to the total negative electrode B- of the battery, and then connect the bar wires (before connecting the bar wires, be sure to pull the bar wires from the plate).
Step 2: Acquisition voltage line welding
Start wiring from the black thin wire at the far right of the row (connected to the total negative terminal of battery B), the second row of wires from the black thin wire to the left of the first thin wire connected to the first series of positive battery (the first battery of the total negative terminal), the third row of wires connected to the second series of positive battery, the fourth row of wires connected to the third series of positive battery… . … In order from right to left, and so on, until the final series of total positive B+.
Step 3: Measure the output voltage
Finally, measure whether the total voltage of the battery and the output voltage of the protection board are equal, equal protection board is working normally.
